Introduction to Rigid Mineral Wool Insulation
Rigid mineral wool insulation is a type of insulation material made from natural minerals such as basalt or diabase. These minerals are melted at high temperatures and spun into fibers, which are then bound together to form rigid boards or panels. Rigid Mineral Wool Insulation

The main advantages of rigid mineral wool insulation include excellent thermal insulation performance, which can effectively reduce heat transfer and energy consumption in buildings. It also has good fire – resistance properties, as it will not burn or melt even at high temperatures, providing a high level of fire protection. In addition, it has good sound – absorption capabilities, helping to reduce noise transmission. The material is also resistant to moisture, fungi, and pests, ensuring long – term durability.
